The present development is a method for generating pure hydrogen from an organic acid solution and a zero-valent metal. By reacting the metal with the organic acid rather than a mineral acid, hydrogen generation occurs at a gradual and more consistent rate than is observed by prior art methods, making the present method suitable for fuel cell applications. A portable hydrogen- generating device using the method of generating pure hydrogen from acidic solution is further disclosed.
L'invention concerne un dispositif de production d'hydrogène pur à partir d'une solution d'acide organique et d'un métal de valence nulle. En mettant à réagir le métal avec l'acide organique plutôt qu'avec un acide minéral, la production d'hydrogène se produit à un taux progressif et plus stable que celui observé avec les procédés antérieurs, ce qui prédispose ce procédé pour des applications de piles à combustible. Par ailleurs, l'invention concerne un dispositif de production d'hydrogène portatif qui applique ce procédé pour obtenir de l'hydrogène pur à partir d'une solution acide.
